I build code generators and developer tooling, mostly around databases and type-safe APIs.

Most of my work is codegen: you describe your data once, and the tooling emits the validators, routers and services that would otherwise be written by hand and drift out of sync.
The largest is prisma-zod-generator, which
turns a Prisma schema into Zod schemas. Across my packages that comes to roughly 127,000 downloads a week.
Alongside it: generators for Joi, Yup, class-validator and Valibot, permission layers for tRPC and oRPC
(trpc-shield, orpc-shield), a codegen suite for Drizzle ORM (DRZL), and a set of Firebase and
Firestore utilities.
Currently working on extensions for Prisma Next, starting with prisma-next-zod-json, which adds typed JSON columns validated by Zod.

Stars and downloads are refreshed weekly by a workflow; downloads are all-time npm totals.

DRZL is adapter-based codegen for Drizzle: Zod, Valibot and ArkType validators, typed CRUD services, and oRPC routers from your existing schema.
